(#) Manifest Resource References

!!! ERROR: Manifest Resource References
   This is an error, and is also enforced at build time when
   supported by the build system. For Android this means it will
   run during release builds.

Elements in the manifest can reference resources, but those resources
cannot vary across configurations (except as a special case, by version,
and except for a few specific package attributes such as the application
title and icon).

(##) Example

Here is an example of lint warnings produced by this check:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~text
AndroidManifest.xml:6:Error: Resources referenced from the manifest
cannot vary by configuration (except for version qualifiers, e.g. -v21).
Found variation in mcc [ManifestResource]
    &lt;application android:fullBackupContent="@xml/backup"&gt;
                                            -----------
AndroidManifest.xml:8:Error: Resources referenced from the manifest
cannot vary by configuration (except for version qualifiers, e.g. -v21).
Found variation in en-rUS [ManifestResource]
    android:process="@string/location_process"
                     ------------------------
AndroidManifest.xml:9:Error: Resources referenced from the manifest
cannot vary by configuration (except for version qualifiers, e.g. -v21).
Found variation in watch-v20 [ManifestResource]
    android:enabled="@bool/enable_wearable_location_service"&gt;
                     --------------------------------------

(##) Suppressing

You can suppress false positives using one of the following mechanisms:

* Adding the suppression attribute `tools:ignore="ManifestResource"`
  on the problematic XML element (or one of its enclosing elements).
  You may also need to add the following namespace declaration on the
  root element in the XML file if it's not already there:
  `xmlns:tools="http://schemas.android.com/tools"`.

* Using a special `lint.xml` file in the source tree which turns off
  the check in that folder and any sub folder. A simple file might look
  like this:
  ```xml
  &lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;lint&gt;
      &lt;issue id="ManifestResource" severity="ignore" /&gt;
  &lt;/lint&gt;
  ```
  Instead of `ignore` you can also change the severity here, for
  example from `error` to `warning`. You can find additional
  documentation on how to filter issues by path, regular expression and
  so on
  [here](https://googlesamples.github.io/android-custom-lint-rules/usage/lintxml.md.html).

* In Gradle projects, using the DSL syntax to configure lint. For
  example, you can use something like
  ```gradle
  lintOptions {
      disable 'ManifestResource'
  }
  ```
  In Android projects this should be nested inside an `android { }`
  block.

* For manual invocations of `lint`, using the `--ignore` flag:
  ```
  $ lint --ignore ManifestResource ...`
  ```

* Last, but not least, using baselines, as discussed
  [here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
